How Loud Is a Clothes Dryer? What Is Actually Declared
For dryers the evidence divides by geography: Europe requires a declared figure, and the United States requires nothing.
Reviewed by our team against authoritative public-health sources. See our editorial standards.
Measurement context
One model's declaration is not a category average, and heat-pump, condenser and vented designs have different noise sources. Treat 63 as an example of a real filing, not as the typical dryer.
Personal exposure
Not determined by these published figures. No safe listening time can be inferred.
Quick Answer
Tumble dryers sold in the EU must declare an airborne acoustical noise emission figure in dB(A) re 1 pW together with a noise class, now under Regulation (EU) 2023/2534, which replaced the earlier 392/2012 labelling rules. One published EPREL fiche, for the AEG heat-pump condenser dryer TR838NBCE, declares 63 dB(A) re 1 pW in class B. In the United States we found no mandatory noise disclosure for residential dryers at all, so figures quoted for US models come from manufacturer marketing rather than a regulated declaration. As with washers and dishwashers, the declared value is sound power, not a level measured where you stand.

What Europe requires, and what it means
The current EU labelling regulation for household tumble dryers is 2023/2534, which together with the ecodesign regulation 2023/2533 replaced the 2012 framework. It requires a declared acoustic airborne noise emission value in dB(A) re 1 pW and an accompanying class.
The measurement method behind it comes from the IEC 60704 test-code series, with part 2-6 covering tumble dryers specifically. As with the other appliance labels, the result is a sound power level determined in a laboratory: the total acoustic energy radiated, not the pressure at a listening position.
The AEG TR838NBCE fiche is a concrete example of the output — 63 dB(A) re 1 pW, class B — filed in the Commission's EPREL database for a heat-pump condenser machine.
Why the dryer type changes the noise source
A heat-pump dryer runs a compressor. A condenser dryer runs a fan and a heat exchanger. A vented dryer pushes air through a duct to the outside. Those are three different noise mechanisms, and they produce different character as well as different levels.
A compressor contributes a continuous low-frequency component that carries through walls and floors well; duct noise in a vented machine depends on the installation as much as on the appliance. This is why one declared figure is a poor guide to how intrusive a specific machine will be in a specific room.
None of the sources we reviewed publishes declared figures grouped by dryer type in a way that would let us state a range per design, so we do not.
| Question | Status in the sources reviewed |
|---|---|
| Declared sound power, EU models | Documented — dB(A) re 1 pW with a class, filed in EPREL under Regulation (EU) 2023/2534 |
| Example declared value | AEG TR838NBCE: 63 dB(A) re 1 pW, class B |
| Mandatory US noise disclosure | None found — no DOE or EPA requirement located |
| Sound pressure at a stated distance | Not found in any agency or peer-reviewed source |
| Declared values grouped by dryer type | Not found — we cannot state a per-design range |
| Power-to-pressure conversion method | Not published for this appliance class |
This table records the state of the evidence rather than measurements. Rows marked as not found are gaps in the published record, not estimates withheld.
The American blank space
This is an unusual case where the absence of evidence is itself the finding. We looked for a US federal requirement to declare dryer noise and found none.
That has a practical consequence for anyone comparing products across markets: an EU figure and a US figure are not two measurements of the same thing. The first is a regulated laboratory declaration with a defined unit and method; the second, when it exists, is a manufacturer's own number, often without a stated weighting, distance, or indication of whether it is power or pressure.
When a specification sheet gives a bare number with no unit beyond "dB", it cannot be compared with anything, and we do not repeat such figures on this page.
What you can usefully measure
Two comparisons are informative in a home. First, the same dryer in the same room at different load sizes, which shows how much of the noise is tumbling rather than machinery. Second, the same dryer heard in the adjacent room, which shows how much your building transmits.
Uncalibrated our meter reports A-weighted digital signal level in dBFS, which is relative rather than sound pressure; after a one-time local calibration it reports an estimated dBA figure. Neither figure is comparable with the declared sound power on the label.
Frequently Asked Questions
How many decibels is a tumble dryer?
EU models declare a sound power figure in dB(A) re 1 pW with a class; one AEG heat-pump model files 63 in class B. That is a laboratory emission figure for a specific model, not a level measured in your utility room.
Which regulation covers dryer noise labelling?
Regulation (EU) 2023/2534 for energy labelling, alongside 2023/2533 for ecodesign. These replaced the earlier 392/2012 framework, so older references to it are out of date.
Are heat-pump dryers quieter?
They have a different noise source — a compressor rather than a strong heating and airflow arrangement — which changes the character as well as the level. We found no published data grouping declared figures by dryer type, so we cannot state a general rule.
Do US dryers have a noise rating?
We found no mandatory US disclosure requirement. Numbers on US listings come from manufacturers and often omit the weighting, the distance, and whether the figure is sound power or sound pressure.
Why does my dryer seem louder than 63 dB?
Because the declaration is sound power radiated by the machine, and what reaches you is pressure shaped by your room, the floor it stands on and your distance from it. Those are different quantities.
Can I compare my phone reading with the label?
No. A phone measures pressure at one point in your room; the label reports sound power determined under laboratory conditions.
